RefME is a great tool for saving sources and creating bibliographies. I've been in love with it since I first started using it last year. RefME is continuously adding more features to help students save sources and generate bibliographies. One of the tools that they added this fall was a Safari extension.
The RefME Safari extension allows students to save web addresses in their RefME accounts by simply tapping the share button in Safari and selecting RefME. The video below provides an overview of the RefME Safari extension. Complete directions are available at the bottom of this page.

One of the criticisms of tools like RefME is that they aren't always perfect in their formatting of citations, but I think they are still valuable because they help get students into the habit of citing their sources of information and keeping a record of the sources they use. Furthermore, RefME or one of the other bibliography generators does make a mistake you can turn that into a teaching opportunity with your students. Point out the flaw and how to correct it.
